RELATED APPLICATION

The present application claims priority to U.S. Provisional Patent Application No. 62/577,319, filed on Oct. 26, 2017, entitled “INTELLIGENT LIGHTING CONTROL SYSTEM POWER HARVESTING APPARATUSES, SYSTEMS, AND METHODS,” which application is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application relates generally to the field of lighting control systems.

BACKGROUND

Customizing and automating home lighting control devices is often epitomized by the installation of unsightly lighting switches that are inundated with light switches confusingly mapped to respective fixtures. Automated home lighting control systems can also include large, complex, expensive central hubs that require expert or skilled technicians for installation and/or operation. Smart light bulbs and/or Wi-Fi enabled lightbulbs introduced into any of these contexts or even in simpler ones can disadvantageously be limited by the light switch that it is associated with and/or the lighting fixture itself. For example, if a light switch associated with a smart light bulb is switched off the smart light bulb becomes inoperable.

The operability of home lighting control devices can also impacted by the wiring associated with a home or location. For example, in some homes that are older or do not have recently updated wiring, the lighting fixtures and switches may be connected to wiring that does not include a neutral wire. This can impact how a bulb responds and/or how a lighting control device operates with particular types of lighting systems and light bulbs.

DETAILED DESCRIPTION

Following below are more detailed descriptions of various concepts related to, and exemplary embodiments of, inventive systems, methods and components of lighting control devices.

FIG. 1A is a perspective partially exploded view of a lighting control device 100. The lighting control device 100 includes a switch module 102 including a light switch actuator 106 and a tactile display 104 housed in the light switch actuator 106. The lighting control device 100 also includes a wall plate cover 108 including a switch module opening 110 extending therethrough. The lighting control device 100 also includes a base module 112 configured for coupling to the switch module 102 via multi-pin socket 114. The base module 112 is sized and configured for receipt within a one-gang wall electrical box and has a volume corresponding substantially thereto. The base module 112 is configured to be coupled to a wall electrical box via connection tabs 116 and fastener apertures 118 in the connection tabs 116.

The light switch actuator 106 includes an outer actuation surface 122, which as discussed further herein may be composed of glass. The actuation surface 122 is movable, for example, by pushing on the curved foot 120 to cause the light switch actuator 106 to pivot, for example. The pivoting of the light switch actuator 106 and the actuation surface 122 causes a contact component (shown in FIG. 2) of the switch actuator 106 to move from a first position to a second position. Movement of the contact component causes a connection of an electrical flow path, for example by allowing two electrical contacts to connect or by connecting the contact component with an electrical contact. The connecting of the electrical flow path, permits electrical energy supplied by a power source connected to the base module 112 to energize or activate the tactile display 104, as discussed in further detail herein. The tactile display 104 is structured in the switch module to move contemporaneously with at least a portion of the actuation surface 122 and with the actuator 106. When activated or energized, the tactile display 104 allows a user to define or select predefined lighting settings where the lighting settings change the voltage or power supplied to one or more light fixtures. The change in power supplied to the light fixtures may include a plurality of different voltages supplied to each fixture and may be based on various parameters including, but not limited to, location, light intensity, light color, type of bulb, type of light, ambient light levels, time of day, kind of activity, room temperature, noise level, energy costs, user proximity, user identity, or various other parameters which may be specified or detected. Furthermore, the lighting control device 100 may be connected to all of the lights in a room or even in a house and can be configured to operate cooperatively with one or more other lighting control devices 100 located in a unit or room and connected to the same or distinct lighting fixtures.

FIG. 1B is a fully exploded view of the lighting control device 100 of FIG. 1A. As demonstrated in FIG. 1B, the tactile display 104 is positioned between the outer actuation surface 122 and the light switch actuator 106. The actuation surface 122 may be composed of an impact-resistant glass material permitting light from the tactile display 104 and/or a clear sight of path for sensors 127 or other lights, such as a light from light pipe 126 indicating activation to pass through the actuation surface 122. The tactile display 104 is composed of a polymer-based capacitive touch layer 124 and a light emitting diode panel 125, which are controlled via one or more modules or processors positioned on the printed circuit board 129. The tactile display 104 is housed within a recess 131 of the light switch actuator 106 beneath the actuation surface 122. The light switch actuator 106 may be formed as a thermoplastic housing including a housing cover 133 and a housing base 135. The light switch actuator housing cover 133 is pivotally connected to the housing base 135 via pins 136 and the housing cover 133 is biased with respect the housing base 135 via torsion spring 137. In particular embodiments, the light switch actuator housing cover 133 may be configured to slide or otherwise translate or rotate. The outer actuation surface 122 is biased with the switch actuator housing cover 133 and moves contemporaneously therewith in concert with the tactile display 104 housed in the cover component 133 of the light switch actuator 106. The light switch actuator 106 includes a switch pin 128 movable between positions to close an open circuit on the primary printed circuit board substrate 150, which board also houses a switch controller or processor. In certain embodiments the light switch actuator 106 may include a circuit board stack, including the primary printed circuit board substrate 150 and a secondary printed circuit board 138 The light switch actuator 106 may include a latch 136 for coupling to the base module 112 (e.g. as the light switch actuator 106 is passed through the opening 110 in the wall plate cover 108), which latch causes the light switch actuator 106 to click into place. The housing base 135 includes a multi-pin connector or plug 134 configured to engage the multi-pin socket 114 of the base module 112.

The lighting control device 100 includes a mounting chassis 142 configured to be installed to an electrical wall box. The mounting chassis 142 creates an even surface for installation of the other modules (e.g., the base module 112 and the switch module 102). Once the base module is connected to the electrical wall box via the mounting chassis 142, the wall plate cover 108 can be coupled to the mounting chassis 142 and the light switch actuator 106 can be inserted through the switch module opening 110. In particular embodiments, the wall plate cover can be coupled to the mounting chassis 142 and/or the tabs 116 of the base module via magnets. The magnets may be recessed within openings of a portion of the wall plate cover 108. As noted, the base module 112 is configured to be coupled to the mounting chassis 142 via connection tabs 116. The base module 112 is further configured to be electrically coupled to a power source (e.g., an electrical wire coming from an electrical breaker box to the electrical wall box) and to one or more light fixtures wired to the electrical box. Accordingly, the base module 112 provides an interface between a power source, the light switch actuator 106, and one or more light fixtures. The base module includes a processor 140 and a circuit board 141 for managing the power supplied by the power source and routed to the one or more light fixtures in accordance with a light setting selection identified via the light switch actuator 106 or the tactile display 104.

One or more of the processor on the printed circuit board 138 a or 138 b 130 and the base module processor 140 may include wireless links for communication with one or more remote electronic device such as a mobile phone, a tablet, a laptop, another mobile computing devices, one or more other lighting control devices 100 or other electronic devices operating in a location. In certain implementations the wireless links permit communication with one or more devices including, but not limited to smart light bulbs, thermostats, garage door openers, door locks, remote controls, televisions, security systems, security cameras, smoke detectors, video game consoles, robotic systems, or other communication enabled sensing and/or actuation devices or appliances. The wireless links may include BLUETOOTH classes, Wi-Fi, Bluetooth-low-energy, also known as BLE (BLE and BT classic are completely different protocols that just share the branding), 802.15.4, Worldwide Interoperability for Microwave Access (WiMAX), an infrared channel or satellite band. The wireless links may also include any cellular network standards used to communicate among mobile devices, including, but not limited to, standards that qualify as 1G, 2G, 3G, or 4G. The network standards may qualify as one or more generation of mobile telecommunication standards by fulfilling a specification or standards such as the specifications maintained by International Telecommunication Union. The 3G standards, for example, may correspond to the International Mobile Telecommunications-2000 (IMT-2000) specification, and the 4G standards may correspond to the International Mobile Telecommunications Advanced (IMT-Advanced) specification. Examples of cellular network standards include AMPS, GSM, GPRS, UMTS, LTE, LTE Advanced, Mobile WiMAX, and WiMAX-Advanced. Cellular network standards may use various channel access methods e.g. FDMA, TDMA, CDMA, or SDMA. In some embodiments, different types of data may be transmitted via different links and standards. In other embodiments, the same types of data may be transmitted via different links and standards.

FIG. 2A shows the lighting control device 100 of FIG. 1A mounted on a wall 200. As demonstrated in FIG. 2A, the base module 112 is not visible upon installation of the lighting control device 100 in view of the wall plate cover 108. Because the wall plate cover 108 attaches to the base module 112, the wall plate cover 108 appears to be floating on the wall 200. The lighting control device 100 may be activated by a user 103 interacting with the outer actuation surface 122 and the tactile display 104.

FIGS. 2B and 2C illustrate multi-switch configurations of multiple lighting control device. FIGS. 2B and 2C illustrate a two switch and three switch embodiment respectively where the lighting control devices 202 and 203 each include a light switch actuator 106 as well as auxiliary switches 204 and 208, as well as 2 and 3 base modules 112, respectively.

FIGS. 3A-3F illustrate a lighting control device transitioning through various lighting settings and a room having lighting fixtures controlled by the lighting control device.

In FIG. 3A, the lighting control device 300 is connected to a base module positioned behind the wall plate 308. The lighting control device 300 includes a dynamic light switch actuator 306, operable in a manner similar to the light switch actuator discussed in connection with FIGS. 1A-2C, and an auxiliary light switch actuator. As demonstrated in FIG. 3A by the unilluminated outer actuation surface 322 of the light switch actuator 306 is inactive and not energized. In response to a user 103 moving the actuation surface 322 of the light switch actuator 306, the light switch actuator 306 begins to become energized, as shown in FIG. 3B. The energization or activation of the light switch actuator 306 is signaled by the power light indicator 305 and by full lighting setting icon 351. As shown in FIG. 3C where the icon 351 is fully lit (rather than partially lit as in FIG. 3B), the light switch actuator 306 is fully energized. In this particular configuration, the primary lights 309 and 310 are illuminated at full power. FIG. 3D shows the transition between lighting settings. As demonstrated in FIG. 3D, this transition is facilitated via user 103 completing swiping gesture 312 across the tactile display 304 and along the actuation surface 322. As the user completes the gesture 312, the icon 351 is swiped from the tactile display 304 as the tactile display toggles to a new light setting shown in FIG. 3E. The new light setting shown in FIG. 3E is represented or identified by the dinner icon 352. The new light setting shown in FIG. 3 has the light fixture 309 powered down and has caused lamp 316 and sconces 318 to become illuminated to change the lighting scene in the room. The change in the light setting causes a change in distribution of power to certain lighting fixture based on the selected lighting setting. The light switch actuator 306 may be pre-programmed with a plurality of lighting settings or may be configured with particular lighting settings as specified by the user 103. A further swiping gesture 315 shown in FIG. 3F or a different gesture are used to transition from the lighting setting of FIG. 3F represented by icon 352 to a further lighting setting.

FIG. 4 provides a flow diagram of operations of a system for controlling a lighting control device. FIG. 4 illustrates control operations of a control system, such as processor 130 configured to control the lighting control device 100 or 300, in accordance with various embodiments of the present invention. At 401, the tactile display housed in the light switch actuator is activated by moving the light switch actuator, for example by moving the actuation surface of the light switch actuator. At 402, the light fixtures electrically coupled to the light switch actuator via a base module are powered as the movement of the light switch actuator causes a contact component to move into a new position and thereby permit or cause an electrical flow path between a power source and the light fixture(s) to be closed. The tactile display housed in the light switch actuator is moved contemporaneously with the actuation surface. At 403, a lighting setting selection request is received via the tactile display, for example by a particular motion or motions on the tactile display. The lighting setting selection request identifies a lighting setting from among a plurality of lighting settings. A user may swipe multiple times to toggle through the plurality of lighting settings or may conduct a specific motion that corresponds to a particular lighting setting including, but not limited to, a half swipe and tap to achieve a light intensity of all the connected light fixtures at half of their peak output. The lighting settings identify distinct power distribution schemes for one or more light fixtures connected to the light switch module. At 404, a power distribution scheme is identified. At 405, the identified power distribution scheme is transmitted, for example by the base module responding to control signals from the light switch actuator, to adjust one, some, or all of the lights based on the power distribution scheme corresponding to the lighting setting selected. The power distribution schemes or profiles may be stored in a memory device of the lighting control device. In certain embodiments, the power distribution schemes may be adjusted to account for other parameters such as ambient lighting from natural light or an unconnected source. In certain embodiments the power distribution schemes may be adjusted based on one or more other sensor parameters. In particular embodiments, the lighting setting may be adjusted by automation based on time of day, sensed parameters such as light, temperature, noise, or activation of other devices including, but not limited to, any electronic device described herein.

FIG. 5 shows a flow diagram of system for remotely operating a lighting control device. In particular embodiments, the lighting control device 100 or 300 may be operable from a remote device if the actuator switch is activated or energized. In such instances, the remote device may include one or more computer program applications, such as system 500, operating on the device to communicate with and control the lighting control device. Accordingly, at 501, the control system 500 initiates a connection module to generate a communication interface between a mobile electronic device and a light switch module. The connection module may cause the remote device to send one or more wireless transmission to the lighting control device via a communication protocol. At 502, the control system 500 causes the remote device to generate a display of icons on a display device of the mobile electronic device to facilitate selection of a lighting setting. At 503, the control system 500 receives a lighting setting selection based on the user selecting a particular icon. At 504, a transmission module causes the lighting setting selected to be transmitted to the lighting control device so that the light switch module and/or the base module can cause the power distribution scheme corresponding to the lighting setting to be transmitted to the lighting fixtures. The tactile display of the lighting control device may be updated in concert with receipt of the lighting setting to display the icon selected on the mobile electronic device and corresponding to the lighting setting selected on the tactile device.

FIG. 6 illustrates a flow diagram of a system for remotely configuring operations of a lighting control device. The remote device may include devices including, but not limited to a mobile phone, a mobile computing device or a computing device remote from the light control device. At 601, the mobile electronic device generates a communication interface with the light switch module. At 602, a light fixture identification module initiates a sensor based protocol to identify a parameter associated with one or more light fixtures connected to the light switch control module. At 603, a display selection module causes a display of an icon to appear on a display device of the mobile electronic device. At 604, a lighting setting configuration module allows a user to create a power distribution scheme or profile for the light fixtures identified based on the identified parameters and a user specified input related to light intensity. At 604, a storage module is used to the store the power distribution scheme and associate a particular lighting setting icon with the power distribution scheme. At 605, a transmission module transmits the power distribution scheme and the associated icon to the light switch control module.

FIG. 7A is a schematic of a circuit for an LED bulb. As desmonstrated in FIG. 7A the LED bulb circuit 700 includes a capacitor 771 upstream of the light emitting element(s) diodes 771. In the case of a non-neutral configuration (i.e. a luminaire connected to a lighting control system without a neutral wire) a lighting component such as and LED bulb with only a line and load connected as its current path provides the only direct path to ground/neutral through the load connection. If the load connection contains a lighting element such as in a LED or CFL light bulb, the only steady state current path is through the light emitting element, which will cause the load to illuminate. Since LED and CFL light bulbs have large capacitance at their input and capacitors conduct current until they are fully charged, a current path through the load connection provides a current path through the load without illuminating the light emitting element. The current path can be used instead to charge a energy storage device in a lighting control system, such as system 100, for a short period of time if the current path is closed for a period of time before illumination occurs.

FIG. 7B-7D are graphs that illustrate the response of the LED bulb to current flow. These figures show the characteristics of the capacitor, desmontrating that at certain frequencies the capacitor behaves as a dead short wire. In the case of load on an AC line such as light bulb, this becomes a path to ground/neutral and the path where all the current will flow, disabling the remaining components of the bulb circuit.

FIG. 7E illustrates modulation of current flow to an LED bulb. The high frequency signal can be achieved by modulating the AC signal from the light control module such as lighting control module 100 or module 7100 of FIG. 7F. The frequency at which the AC signal is chopped can be varied based on the capacitance of the load (e.g. the capacitance of capacitor 771 of the light bulb.) This capacitance can be determined through incremental testing, measurement, or given based on the specific bulb. The frequency at which the AC signal is chopped can be varied to deliver equal power during each period

FIG. 7F illustrates a schematic of a lighting control system for modulating the current flow to an LED bulb with a capacitor such as FIG. 7A according to a modulation, such as FIG. 7E. The modulation of the AC signal transmitted from the lighting control system 7100 to the luminaire 7700 containing the capacitance based light bulbs can be controlled via controller 7103 causing a switching circuit to open and close to connect and disconnect a line voltage to the load of the luminaire 7700. When the circuit is closed the energy storage device 7104 (e.g. a capacitor or rechargeable battery) can be charged through the closed circuit via the line voltage before the capacitor in the lightbulbs connected to luminaire 7700 are charged. In some implementations, the controller 7103 is configured to run a test protocol prior to temporarily closing the circuit to determine an illumination period, the illumination period defining how long it takes for the closed circuit to illuminate the light emitting element, wherein during the test protocol the circuit is closed until the light emitting element is illuminated and thereafter the controller is set to temporarily close the circuit for a charging time period/frequency/power that is less than the illumination period.

FIG. 8 is a schematic of a lighting control system 800 configured to execute certain lighting control operations described herein. The lighting control system 800 illustrates lighting control system components that can be implemented with a lighting control system including an air gap system as described herein. The lighting control system 800 is depicted separated into a base lighting control module 812 (which may be configured in a manner similar to base module 112) and a switch module or switch controller 802 (which may be configured in a manner similar to switch module 102). As described herein, the switch module 802 can include a tactile interface, operable via the graphical user interface module 852, and a switch actuator, such as the tactile display 104 and the light switch actuator 106 described herein. The switch module 802 houses a processor 850, which may be configured to send commands to microcontroller 840 and receive inputs from the micro-controller 840 to control the operation of a transformer 818, a power isolator and an AC to DC converter 814 (which may include a flyback converter), and a dimmer, such as a TRIAC dimmer 813, a voltage and current sensor 816. In some embodiments, the base lighting control module 812 may include a MOSFET dimmer. The power isolator 814 separates the analog AC current from the low power or DC digital components in the base lighting control module 812 and the switch module 802. The power isolate 814 may provide power inputs to the switch control module 802 via a power module 853. Power module 853 includes power circuitry configured to regulate the flow of power from the base module 812 to the switch controller module 802 including directing power to one or more of the modules in the switch controller module 802. The switch module 802 also houses a communication module, which can include one or more antennae or other wireless communication modules. The switch module 802 also houses a sensor module, which can include one or more sensors, such as a light sensor, a camera, a microphone, a thermometer, a humidity sensor, and an air quality sensor. The processor 850, is communicably coupled with one or more modules in the switch module 802 to control the operation of and receive inputs from those modules, for example to control modulation of the flow of electrical energy to a lighting circuit of a light fixture 824 connected to the base lighting control module 812.

The base lighting control module 812 includes a ground terminal 830 for grounding various electrical components container in the module 812. The base light control module 812 includes a neutral terminal 828 for connecting to a neutral wire, a line terminal 826, and a load terminal 822. As shown in FIG. 8, the voltage and current sensor(s) are coupled to the load line to detect changes in the voltage or current along the line carrying power to one or more light fixtures 824 connected to the lighting circuit (750). The base lighting control module 812 also includes a controller 840 communicably coupled to the processor 850. The base lighting control module 812 also includes LED indicator lights 842 and 841 for indicating information regarding the status of the base lighting control module 812. For example, in some embodiments LED indicator light 841 can indicates if a neutral wire is connected while LED indicator light 842 can indicate if a 3 way connection is connected.

FIG. 9 describes an implementation of lighting control system 900 that includes multiple lighting control subsystems that are distributed over a building (e.g., house, office etc.), for example, in different rooms of the building. In the implementation of the lighting control system 900 illustrated in FIG. 9A, rooms 902 a-d have distinct lighting control systems. For example, the lighting control system of room 902 a includes lighting control device 904 a, lighting circuit 910 a, light sensors 906 a and motion sensors 908 a. The lighting control system 900 can include a central lighting control device 904 that serves as a central control for the lighting control system 900. In certain embodiments, the central lighting control device 904 can include a lighting control system such as system 100 or 800.

The lighting control system of room 902 a, which comprises lighting control device 904 a, light sensor 906 a, motion sensor 908 a and lighting circuit 910 a, is discussed. However, the concepts and applications discussed are not limited to the lighting control system in the room 902 a and can be generally applied to lighting control systems in other rooms (e.g., 902 b-d) or lighting control subsystems that may distributed over more than one room.

The light sensor 906 a is configured to detect ambient light (which can include natural light and/or light from a light fixture connected to the lighting circuit 910 a), for example by converting the electromagnetic energy (e.g., photon energy) into an electrical signal (e.g., a current or a voltage signal). The electrical signal can be communicated to the lighting control device 904 a. The light sensor 906 a can include one or more photo-resistors, photodiodes, charge coupled devices etc. The light sensor 906 a can include a light filter that preferentially allows certain frequencies of light to be transmitted and therefore detected by the light sensor 906 a. For example, the light filter can be configured to transmit frequencies that correspond to the light emanating from the lighting circuit 910 a. This can allow the light sensor (e.g. 906 a) to preferentially detect light from the lighting circuit 910 a while filtering out light generated by other sources. For example, if the light sensor is located in a room that receives ambient natural light (e.g., daylight), the light sensor can substantially filter out the ambient natural light and primarily detect light from the lighting circuit 910 a. The light sensor 906 a can also be configured to efficiently and accurately detect a range of light intensities, for example, the range of intensities that can be produced by the lighting circuit 910 a. This can allow the light sensor 906 a to efficiently and accurately detect light for various intensity settings of the lighting circuit 910 a.

The motion sensor 908 a can be configured to detect motion in the room 902 a. For example, the motion sensor can detect movement of an occupant in the room 902 a. The motion sensor 908 a can include one or more of passive sensors (e.g., passive infrared (PIR) sensor), active sensors (e.g., microwave (MW) sensor, ultrasonic sensors etc.) and hybrid sensors that include both passive and active sensor (e.g., Dual Technology Motion sensors,). The passive sensors do not emit any energy and detect changes in energy of the surrounding. For example, a PIR sensor can detect infrared energy emitted by the human body (due to the temperature associated with the human body). Active sensors, on the other hand, emit electromagnetic or sonic pulses and detect the reflection thereof. For example, MW sensor emits a microwave pulse and detects its reflection. Hybrid sensors can include both active and passive sensors and therefore motion can be sensed both actively and passively (hybrid sensing). Hybrid sensing can have several advantages, for example, the probability of false positive detection of motion can be smaller in hybrid sensors compared to active/passive sensors.

The lighting control device 904 a is configured to communicate with the light sensor 906 a and motion sensor 908 a. The motion sensor 908 a can send a notification signal to the lighting control device 904 a conveying that motion has been detected in an area proximal to the lighting circuit 910 a, for example, in the room 902 a. The light sensor 906 a can send a notification signal to the lighting control device 904 a conveying that light emanating from the lighting circuit 910 a has been detected. Additionally, the notification signal can include information about the properties of the detected light, e.g., intensity, bandwidth etc. The lighting control device 904 a can store data representative of the notification signals received from the motion and light sensors in a device database. The lighting control device 904 a can include a clock and/or a timer that allows the lighting control device 904 a to track the time and/or duration of the received signals from the light sensor 906 a and motion sensor 908 a. The tracking time and/or duration information can be also be stored in the device database.

The lighting control device 904 a can be configured to receive and transmit data through the internet. The lighting control device 904 a can, for example, infer information about ambient natural light from data about the weather conditions, daylight hours etc. from online databases (e.g., databases of weather.gov, gaisma.com, noaa.gov wunderground.com etc.). For example, the received data can include information about the sunrise and sunset times in the geographical area associated with the lighting control system 900 and the time of the year. Based on this, the lighting control circuit 904 a can infer the time period during which no ambient natural light is available. In another example, the received data can contain information about the weather conditions. The lighting control circuit 904 a can infer, for example, that overcast conditions can lead to reduction in natural ambient light. The lighting control device 904 a can save the data and/or inferred information in the device database. This can allow the lighting control device 904 a to infer patterns between the usage of the lighting circuit 910 a and ambient natural light conditions.

The lighting control device 904 a can be configured to determine one or more properties of the lighting circuit 910 a. For example, device 904 a can determine the type (e.g., incandescent, fluorescent, LED, halogen, high intensity discharge, full spectrum, UV, black light, antique, vintage) and the wattage of the light bulbs associated with the lighting circuit 910 a. The light control device 904 a can also search online databases for information about the detected light bulbs. For example, the lighting control device 904 a can download specifications (e.g., information about voltage, wattage, luminescence, dimmability, average life etc.) from online databases of the manufacturers of the detected light bulb. The lighting control device 904 a can also download information related to the light and motion sensors, for example, drivers associated with the light and motion sensors. The determined properties and the downloaded information about the lighting circuit 910 a can be stored in the device database.

The lighting control device 904 a can be configured to receive data and/or instructions from communication device 920 (e.g., cellphone, laptop, iPad, input device such as keypad, touch screen etc.). Additionally or alternately, communication device 920 can be input device (e.g., keypad, touchscreen etc.). For example, the computation device 920 may provide instructions for the operation of the lighting control device 904 a. Based on the instruction, the lighting control device 904 a can switch on/off one or more light bulbs in the lighting circuit 904 a. The computation device 920 can also instruct the lighting control device 904 a to change the operation parameters of the lighting circuit 910 a. For example, the lighting control device 904 a can be instructed to increase/decrease the brightness of the lighting circuit 904 a (e.g., by increasing/decreasing the power suppled to the lighting circuit). The communication device 920 can instruct the lighting control device 904 a to perform one or more of the aforementioned functions at a certain time or after a certain period of time. For example, the communication device 920 can instruct the lighting control device 904 a to set up a timer at the end of which a desired function is performed. Through the communication device 920, information related to the lighting control system 900 can be conveyed to the lighting control device 904 a. For example, a user can input the room-types (e.g., bedroom, kitchen, living room etc.) of the rooms 902 a-d. The user shutdown one or more the lighting control subsystems in room 902 a-d for a desired period of time, for example, when the user will be away for a vacation. The communication device 920 can communicate with the lighting control device 904 a using short-range wireless technology (Bluetooth, Wi-Fi etc.), through a cellular network and/or a physical connection (e.g., Ethernet cable). The data and/or instruction received by the lighting control circuit 904 a from the communication device 920 can be stored in the device database. The time at which the data and/or instruction were received can also be stored in the device database.

The lighting control device 904 a can be configured to communicate information to the communication device 920 and/or an output screen. For example, the lighting control device 904 a may communicate the operational parameters associated with the lighting circuit 910 a (e.g., brightness of the lighting circuit 910 a, tentative time at which the lighting circuit 910 a will be turned on/off, duration of operation of the lighting circuit 910 a etc.). The lighting control device 904 a can communicate notification signal from the light sensor 906 a and motion sensor 908 a to the communication device 920. For example, communication device 920 can be notified that motion or light has been detected in room 902 a.

The central lighting control device 904 can communicate with the lighting control subsystems distributed over the building (e.g., rooms 902 a-d), and provide a central control for the lighting control system 900. The central lighting control device 904 can control the operation of light sensors 906 a-d, motion sensors 908 a-d, lighting circuits 910 a-d and lighting control devices 904 a-d. For example, the central lighting control device 904 can instruct the lighting control device 904 a to change the operating parameters of the lighting circuit 910 a. The central lighting control device 904 can also receive notification signals from light sensors 906 a-d and motion sensors 908 a-d, and communication device 920.

The central lighting control device 904 can include a central device database. Data stored in device databases associated with lighting control devices 904 a-d can be transferred, for example, periodically, to the central device database. In some implementation, the central lighting control device can request specific information from the device databases of lighting control devices. For example, the central control device 904 can request the lighting control device 904 a for information related to one or more of light sensors 906 a, motion sensors 908 a, instructions from communication device 920, etc. FIG. 9B illustrates another implementation of the lighting control system 900. In this implementation the central light control device 904 also operates as the “lighting control device” for the lighting control subsystem associated with room 902 a (which includes light sensor 906 a, motion sensor 908 a and lighting circuit 910 a).

FIG. 10 illustrates an implementation of the central lighting control device 904 as described in FIG. 9B. The central lighting control device 904 comprises lighting circuit system 1010, controller 1020 and communication system 1030. The controller 1020 can control the operation of and receive data from the lighting circuit system 1010 and communication system 1030. The controller 1020 includes a processor 1022 and a storage device 1024. The processor is configured to run applications that control the operation of the lighting control system 900, and the storage device 1024 can store data related to the lighting control system 900 (e.g., central device database, device database etc.).

The lighting circuit system 1010 can transmit electrical power to and detect response of the lighting circuit 910 a. The lighting circuit system 1010 can include a power circuit 1014 that can supply power to the lighting circuit 910 a, and a detector circuit 1012 that can detect the response of the lighting circuit 910 a. The power circuit 1014 can comprise a tunable voltage/current source that can supply an input voltage/current signal to the lighting circuit 910 a. The detector circuit 1012 is configured to detect a response of the lighting circuit 910 a that can include one or more of current, voltage and impedance response. In some implementations, the detector circuit 1012 may include a voltage sensing circuit that can detect a voltage response (e.g., voltage across the lighting circuit 910 a) or a current sensing circuit that can detect a current response (e.g., the current flowing into the lighting circuit 910 a). The power circuit 1014 can also supply power to the light sensor 906 a and the voltage sensor 908 a.

The communication system 1030 is configured to communicate with light sensor 906 a, motion sensor 908 a, and lighting control devices (e.g., 910 a-d in FIG. 9A, 910 b-d in FIG. 9B). For example, the communication system 1030 (e.g., antenna, router etc.) can transmit instructions (e.g., instruction to detect light/motion) from the controller 1020 to the light sensor 906 a and/or motion sensor 908 a. The instructions can be transmitted wirelessly in the 2.4 GHz ISM band using various wireless radio technologies (Wi-Fi, Bluetooth, Low Power Radio (LPR) etc.). Additionally or alternately, the instructions can be transmitted in the form of an electrical signal (e.g., current signal, voltage signal) or optical signal through a physical connection (e.g., transmission line, Ethernet cable etc.). The communication system 930 can be configured to receive notification signals (e.g., through the channels of instruction transmission described above) from the light sensors 906 a and/or motion sensors 908 a and convey the notification signal to the controller 1020.

The communication system 1030 can also be configured to communicate with communication device 920, for example, through a cellular network, wireless radio technology etc. The communication system 1030 can include, for example, a router that allows it to communicate through the internet with websites and online databases. For example, the controller 1020 can instruct the communication system 1030 to access the website of a light bulb manufacturing (e.g., light bulb in the lighting circuit 910 a) and download the relevant specifications. The communication system 1030 can also, for example, download software (e.g., drivers) that can allow the controller 1020 to communicate with the light sensors 906 a and motion sensors 908 a. The communication system 1030 can also download updated operating systems for the controller 1020.

The lighting control device 904 can control the operation of lighting circuits 910 a-d based on notification signals from the light sensors 906 a-d and motion sensors 908 a-d. For example, if the lighting circuit 910 a has been switched on and no motion is observed by the motion sensor 908 a for a predetermined period of time, the control device 904 can automatically switch off the lighting circuit 910 a. The control device 904 can make the determination that the lighting circuit 910 a has been switched on based on notification signal from the light sensor 906 a and/or the response from the detector circuit 1012. The period of time between the last detected motion and the time at which the lighting circuit 910 a is switched off can be based on, for example, an input provided by a user through the communication device 920. This period of time can be different for different rooms. For example, the period of time can be longer for the room 902 a (e.g., bedroom) compared to the room 902 b (e.g., a bathroom).

The lighting control system 900 can be configured to control the operation of the lighting circuits 910 a-d based on analysis of the behavior of one or more users of the system 900 and data acquired by the system 900. The behavior analysis can include, for example, pattern recognition of the notification signals from the light sensors 906 a-d and motion sensors 908 a-d, instructions provided by the user through communication device 920 and information obtained by lighting control device 904 from online databases. For example, the central lighting control device 904 can be notified by the light sensor 906 a that the lighting device 910 a is switched off at approximately a certain time during the weekdays and at approximately a different time during the weekends. Based on this pattern, the lighting control device 904 can set switch off times, which are different for weekends and weekdays, for automatically switch off the light 910 a. Automatic switching off the light 910 s can be suspended if motion is detected by motion sensor 908 a, and notification can be sent to the communication device 920.

The control device 904 can also include information obtained from online databases in its behavioral analysis of the users. For example, the control device 904 can be notified that the user switches on the light 910 a in the mornings of certain days in the year. The device 904 compares this behavior with the weather conditions (known through online databases) and determines that the light 910 a is switched on in the mornings of days when the sky is overcast. Based on this pattern, the control device 904 can automatically switch on the light 910 a on days when the sky is over cast. Additionally, the control device 904 may learn that the weather conditions effect the operation of lighting circuit 910 a but not of lighting circuit 910 b. This may arise from the fact the room 902 a, associated with lighting circuit 910 a, has windows and receives natural ambient light, while room 902 b, associated with lighting circuit 910 b, does not have windows and does not receive natural ambient light. The control device 904 can infer that the operation of lighting circuit 910 b is independent of weather conditions. In some implementations, the control device 904 can change the operating parameters of lighting circuit 910 a based on weather conditions. For example, the control device 904 can change the brightness setting of the lighting circuit 910 b based on the weather conditions.

FIG. 11 illustrates the controller 1020 comprising the processor 1022 and the storage device 1024 and configured to execute light control module 1102. The light control module 1102 can collect, store and analyze data, and determine the operation of a lighting circuit (e.g., lighting circuit 910 a). The light control module 1102 can include a data collection module 1104, system control module 1106, and pattern recognition module 1108. The data collection module can collect data (e.g., data from online databases, detector circuit 1012, communication device 920, notification signals from light sensors 906 a-d and motion sensors 908 a-d etc.) from the communication system 1030 and store the data in the central device database 1112 in storage device 1024. The system control module 1106 controls the operation of lighting circuit system 1010. For example, system control module 1106 can instruct the power circuit 1014 to change the electrical power supplied to the lighting circuit 910 a. The system control module 906 can determine, based on voltage/current response of the lighting circuit 910 a measured by the detector circuit 1012, the type of light bulbs (e.g., incandescent, fluorescent, LED, halogen, high intensity discharge, full spectrum, UV, black light, antique, vintage) therein and store this information in the central device database 1112. The system control module 1106 can also control the operation of the light sensors 906 a-d and motion sensors 908 a-d. For example, it can instruct the light and motion sensors to start or suspend detection of light and motion signals. The pattern recognition module 1108 can include machine learning techniques that use data in the central device database 1112 as “training data” to infer patterns based on which the operating parameters for the lighting circuits 910 a-d can be determined.

FIG. 12 is a flow diagram of a method of operating a lighting control system. At 1201, a circuit connecting the AC line voltage connected to a lighting control system is temporarily closed with the load of a lightbulb (e.g. the switch is temporarily turned on). The period of being closed includes a period of 500 microseconds in accordance with particular embodiments. The period of being closed is configured so as to not fully charge a capacitor in the light bulb structure, so that the light bulb, connected without a neutral wire, is not illuminated. During this period, at 1202, the current flowing through the circuit partially charges an energy storage device of the lighting control system also connected to this circuit. At 1203, the circuit is re-opened to prevent current from the line from flowing to the load. This process is repeated so as to gradually charge the energy storage device of the lighting control system without illuminating the light emitting element of the light bulb.

A computer storage medium can be, or be included in, a computer-readable storage device, a computer-readable storage substrate, a random or serial access memory array or device, or a combination of one or more of them. Moreover, while a computer storage medium is not a propagated signal, a computer storage medium can be a source or destination of computer program instructions encoded in an artificially generated propagated signal. The computer storage medium can also be, or be included in, one or more separate physical components or media (e.g., multiple CDs, disks, or other storage devices).

The apparatus and execution environment can realize various different computing model infrastructures, such as web services, distributed computing and grid computing infrastructures.

A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.

The processes and logic flows described in this specification can be performed by one or more programmable processors executing one or more computer programs to perform actions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., a FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).

Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random access memory or both. The essential elements of a computer are a processor for performing actions in accordance with instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device (e.g., a universal serial bus (USB) flash drive), to name just a few. Devices suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.

To provide for interaction with a user, implementations of the subject matter described in this specification can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, by sending web pages to a web browser on a user's user device in response to requests received from the web browser.

The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a local area network (“LAN”) and a wide area network (“WAN”), an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks).

The computing system can include users and servers. A user and server are generally remote from each other and typically interact through a communication network. The relationship of user and server arises by virtue of computer programs running on the respective computers and having a user-server relationship to each other. In some implementations, a server transmits data (e.g., an HTML page) to a user device (e.g., for purposes of displaying data to and receiving user input from a user interacting with the user device). Data generated at the user device (e.g., a result of the user interaction) can be received from the user device at the server.
